(Just my personal opinion) There are so manyyy things that i would've done differently if i were the creator of the show, first of all, xo kitty should have a consistent colour palette just like tatbilb, i really believe that it would've added a little jenny han magic into it, yk? Second, kitty is all over the place in the worst ways possible, and yes, i know that it's all a part of her character but come on why are like four people in love with her and why can she not do something about it?? She's helpless, honestly. Third, a lott of people say that they wanted for min ho and kitty to have had their first kiss this season, and although i kind of agreed at first, but i think they still need their time to grow, both of them, they keep getting in and out of insecure and tiresome relationship and situations that they need time to navigate their feelings to the right path, to each other.
